Title: Rotation supporting structure for disk filing device
Inventor: YAMADA TOMOYOSHI
IPC: G11B19/20
Filed: 1990-09-14
Abstract: PURPOSE:To reduce the thickness of the whole of a device by setting the inside diameter of the inner ring of two ball bearings, which rotate the support a holder, to a value larger than the outside diameter of the outer ring of the other and arranging them so that they overlap in the axial direction. CONSTITUTION:An inside diameter D of the inner ring of a first ball bearing is made larger than an outside diameter (d) of the outer ring of a second ball bearing 2 so that the second ball bearing 2 can be put in the central aperture area (inner ring area S) of the first ball bearing which is prescribed by an inner ring 1b of the first ball bearing 1. Consequently, length (l) from the lower face of the first ball bearing to the upper face of the second ball bearing can be made shorter than the sum of height (m) and (n) of ball bearings 1 and 2. Since a part of the second ball bearing 2 is put in the inner ring area S of the first ball bearing 1 in this manner, the length between upper and lower end faces of ball bearings 1 and 2 most distant from each other is shorter than the sum of height of both ball bearings. Thus, the thickness of the whole of the device is reduced.

This deciding part 3 decides whether the result of read is a space or not, and in case of a space, information of a format discriminating number store area 5 becomes the format discriminating number 13 of the business form concerned. If said result is other than a space, the result of read becomes the format discriminating number 13 of the business form concerned. Also, the result obtained from the format discriminating number deciding part 3 is transferred to the format discriminating number store area 5 by giving a command to a format discriminating number store part 4, and subsequently, read of a read data 14 is commanded to the OCR mechanism control part 6. By executing repeatedly such asn operation at every business form, business forms (2) 12 are processed by the same read format as business forms (1) 11.

Abstract: PROBLEM TO BE SOLVED: To reduce the size and weight without decreasing the total flux being fed to an armature core by setting the number of poles of field, the angle of pole arc and the thickness of magnet optimally. SOLUTION: A field magnet 1 has 8 poles, the pole arc comprising a main pole 1b and a sub-pole 1c is set at 33.75 deg.

The main pole 1b is longer than the armature core 2a in the axial direction and the axial length Lm thereof is set to satisfy a relationship 1.0<Lm/Lc<1.4, where Lc is the axial length of armature core. Consequently, demagnetization due to armature reaction can avoided even if the thickness of magnet is decreased and the size can be reduced. Furthermore, the characteristics can be sustained without decreasing the total flux and the size and weight can be reduced by decreasing the cross-sectional area of yoke 1a.
